Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting tools, in particular to a saw blade. Background Art
[0002] In modern industrial production, saw blades undoubtedly play a key role, especially when it comes to precise cutting of various materials. However, the use of saw blades often faces a series of technical difficulties when facing certain materials, especially PVC edge banding. PVC has been widely used in the field of board edge banding due to its excellent durability and relatively low cost. However, the high hardness of this material poses a severe challenge to the cutting effect of saw blades.
[0003] The blades of the commonly used saw blades are usually in a rectangular trapezoidal structure after being carefully ground. Although in theory, this design helps to improve cutting efficiency to a certain extent, some unexpected problems often occur in actual operation. Especially when cutting PVC edge banding at high speed, when the blade is about to cut the edge banding, due to the high hardness of the material and the fast cutting speed, the blade often directly tears the remaining edge banding from the main body. This tearing process is not only very likely to cause quality problems such as edge collapse and damage on the edge of the edge banding, seriously affecting the overall appearance and durability of the product, but may also have an adverse effect on subsequent production processes. Utility Model Content
[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes a saw blade.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A saw blade comprises a saw blade base, wherein a central hole is arranged in the middle of the saw blade base, saw teeth are formed on the edge of the saw blade base, and the saw teeth of the saw blade base are not processed with cutting edges.
[0007] Furthermore, a reinforcement member is formed on at least one side of the saw blade base.
[0008] Furthermore, a reinforcement piece is formed on the left side and / or the right side of the saw blade base.
[0009] Furthermore, the reinforcement member is a reinforcement ring, and the reinforcement ring is formed in the middle of the saw blade base.
[0010] Furthermore, the reinforcement ring is integrally formed with the saw blade base.
[0011] Furthermore, the reinforcement member is an annular frame, and the annular frame is attached to the saw blade base.
[0012] Furthermore, the saw blade is detachably connected to a reinforcement piece.
[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model significantly reduces the probability of edge collapse caused by impact during the cutting process by adopting an unsharpened sawtooth design. In addition, the reinforcement design not only significantly enhances the overall stability of the saw blade, so that it can still maintain excellent performance under high load and high-speed cutting conditions, but also greatly prolongs the service life of the saw blade, thereby reducing the production cost and time cost caused by frequent replacement of the saw blade.

[0015] Figure 2 It is the front view of the utility model;
[0016] Figure 3 This is a schematic diagram of the use state of the utility model;

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:
[0019] like Figure 1-Figure 3 As shown, a saw blade 100 is mounted on a motor 200, including a saw blade base 1, a center hole 3 is provided in the middle of the saw blade base, and the design of the center hole is not only convenient for installation and fixing on various cutting equipment, but also ensures the stability of the saw blade when rotating at high speed. In addition, the precise design of the center hole can effectively disperse the stress generated when the saw blade is working, thereby increasing the service life of the saw blade. Saw teeth 2 are formed on the edge of the saw blade base, and a reinforcement member 4 is formed on at least one side of the saw blade base. This reinforcement design can not only effectively prevent the saw blade from deformation or breakage when rotating at high speed or bearing heavy loads, but also significantly improve the overall rigidity and durability of the saw blade, thereby extending its service life.
[0020] Furthermore, the saw teeth of the saw blade base have not been processed for cutting edges. When these saw teeth and the edge band are subjected to grinding action, significant heat will be generated. This accumulation of heat will actually change the physical properties of the edge band, especially increase its elastic modulus. Therefore, at the moment when the edge band is about to be cut, due to the increase in the elasticity of the material, the impact of the saw blade on it will be effectively buffered, thereby avoiding the edge collapse caused by direct tearing. This method of improving the cutting performance of materials through thermal effects provides an effective path to achieve high-quality, edge-free cutting effects.
[0021] Furthermore, a reinforcement member 4 is formed on the left and / or right side of the saw blade base. The reinforcement member can be installed on the left or right side of the saw blade base, and reinforcement members can be installed on both sides of the saw blade base at the same time. This reinforcement design not only makes the saw blade more stable and reliable when subjected to various external forces and stresses, but also further improves the cutting accuracy and efficiency of the saw blade.
[0022] In at least one embodiment, the reinforcement member is a reinforcement ring, which is formed in the middle of the saw blade base, and the reinforcement ring is integrally formed with the saw blade base. This reinforcement ring is formed around the middle of the saw blade base, and is tightly combined with the saw blade base to form an integrally formed solid structure. The presence of the reinforcement ring not only significantly enhances the anti-torsion and anti-deformation capabilities of the saw blade, but also further improves the accuracy and stability of cutting.
[0023] In at least one embodiment, the reinforcement is an annular frame attached to the saw blade base. The design of the annular frame not only optimizes the weight distribution of the saw blade, but also reduces unnecessary material consumption and cost expenditure while maintaining efficient cutting performance of the saw blade.
[0024] In at least one embodiment, the saw blade is detachably connected to a reinforcement member. This connection method not only facilitates the installation, disassembly and maintenance of the saw blade, but also allows the reinforcement members of different specifications or types to be flexibly replaced according to actual needs to meet diverse cutting requirements. At the same time, the detachable design also helps to reduce the waste of resources and the burden on the environment, which is in line with the concept of green manufacturing and sustainable development.
[0025] Working method, fix the PVC material 300 to be cut on the clamp to ensure that the material is stable and motionless for precise cutting. Start the motor 200 to drive the saw blade 100 to rotate. The saw teeth 2 of the rotating saw blade 100 are brought into contact with the PVC material 300. Since the saw blade base 1 is thin and the saw teeth have not been processed for cutting edges, the saw blade mainly cuts the material by friction when it contacts the PVC material. During the cutting process, since the saw blade base is thin, elastic deformation may occur, causing the saw blade base to twist. At this time, the role of the reinforcement 4 is reflected, which can effectively prevent the saw blade base from twisting, thereby ensuring cutting accuracy. When the PVC material is completely cut off, turn off the motor 200 and remove the cut PVC material. After use, clean and maintain the saw blade to ensure its long-term and stable use effect.
[0026] During use, you should pay attention to safety and avoid contact between your hands or other parts of your body and the rotating saw blade. During the cutting process, the saw blade should be kept perpendicular to the PVC material to obtain a more precise cutting effect. After the cutting is completed, the motor should be turned off and the saw blade should be removed in time to avoid unnecessary wear caused by long-term idling.
[0027] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
